Only liked by the public.
I’ve met him and he’s as pretentious in real life as his is on twitter. Actually, no one in my department here likes him.
He hasn’t published anything this century. His last publication was in January of 1998. He worked with the COSMOS project that put out 3 papers in 2007-8, but it was a collab and he didn’t have much to do with them.
These days he basically goes around teaching half-truths and being shady on social media to stay just relevant enough for pop culture nerds to be obsessed with him.
